18 Claims.

This invention relates to awinding apparatus, and it is primarily an obj ct of the invention to provide an apparatus of this kind for wrapping a cord or kindred strand around a base or core member for the production of a slide caster for furniture.

' It is also an object of the invention to providea machine of this kind wherein is provided a support for the core or base member upon which the cord or strand is to be wrapped together with means for intermittently rotating said support in timed sequence with respect to the wrapping unit. i

Another object of the invention is toprovide '1 a'device of this kind provided with means whereby the cord or strand may be readily severed when desired and wherein means are also provided for throwing or adjusting said cutting means into an inoperative position to facilitate 'the application of a core or base to its support as well as the removal of the finished slide caster. A further object of the invention is to provide a device of this kind wherein the winding unit is provided with guide members for the cord or strand and wherein each of said guide members can be adjusted or shifted with respect to the work as the requirements of practice may necessitate.

"An additional object of the invention is to provide an apparatus of this kind comprising a rotatable support for the work together with a revolving winding unit with means driven by the revolving winding unit for intermittently rotating the support thus assuring the desired winding of the cord or other strand.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved winding apparatus whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth. 1

The novel features of my invention will here inafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein j Figure 1 is a view partly in vertical section and partly in elevation illustrating an apparatus constructed in accordance with an embodiment of my invention{ Figure 2 is a fragmentary view in side eleva 'tion of the work support and wrapping unit as herein employed;

Figure 3 is a view partly in section and partly in elevation showing the means herein employed for mounting the'cores or spools and for directing the cord or strand to the bore of the shaft;

Figure 5 is an enlarged fragmentary View partly in horizontal section and partly in top plan illus trating-a means as herein employed for intermittently rotating the work support by the winding unit; V

Figure 6 is a fragmentary sectional View taken substantially on the line 6-6 of Figure 4 looking in the direction of the arrows; Figure 7 is a sectional view taken substantially on the line 7-7 of .Figure 2; i i Figure 8 is a fragmentary view in front eleva tion of 'the guard plate as herein employed.

As disclosed in the accompanying drawings,

1 denotesa table or platform of desired configuration and dimensions and which is adapted to be placed upon any suitable support. One end portion of this table is provided with an upstanding bearing block 2 which rotatably supports an end portion of a shaft 3. Theportion of the shaft 3 disposed through the block 2 is reduced-in diameter, as at 3', and surroiuiding such reduced portion 3' and fixed thereto is a bearing sleeve 4 of brass orother desired material.

The reduced portion 3 of the shaft 3 extends in advance of the bearing block 2 a slight dis-' tance as does also the sleeve 4 and, furthermore, this reduced portion 3 extends slightly in ad- Vance of the applied sleeve 4 and to said extended portion is fixed a disk 5 for rotation with the shaft 3.

The disk 5 is comprised in the twisting unit as herein disclosed and projecting forwardly from said disk at diametrically opposed points are the elongated cylindrical arms 6. These arms 6 are also equidistantly spaced from the axial center of the diskb. The outer end of each of the arms 6 is continued by a reduced threaded extension 7 upon which are threaded sleeves 8 and 9. The outerend of each of these sleeves 8 and 9 is defined respectively by the annular flanges 10 and 11 and each of these flanges at points equidistantly spaced circumferentially therearound adjacent to the periphery thereof is provided with the openings 12 through which a cord or kindred strand C is adapted to be selectively threaded. These sleeves 8 and 9, or more particularly the flanges 10 and 11 respectively thereof, as is believed to be derstood, provide guiding means for a-cord or thread but only one of the flanges 10 or' 11 is employed for such purpose at one time. When the outer or larger flange 11 is employed the sleeve 8 serves as a holding or locking medium for the sleeve 9. When the flange 10 is employed the sleeve 9 is removed from the extention 7 and the use of either of the flanges 10 and 11 is dependent upon the size of the core or base member B upon which a winding is to be made.

By having the sleeves 8 and 9 threaded upon the extension '7 of the arm 6 the flanges 10 or 11 as required may be adjusted lengthwise of the extension 7 to effect a desired placement of a flange 10 or 11 with respect to the work and, furthermore, the threaded mounting of each of the sleeves 8 and 9 permits a ready adjustment of either of the flanges 10 or 11 to obtain a desired adjustment of a guide opening 12 with respect to the work. By providing a plurality of openings 12 the ready adjustment of a sleeve 8 or 9 need not be to very great extent as in fact such adjustment need only be made for a distance equal to one-half of the spacing between adjacent openings 12. 1

Fixed upon the arms 6 at desired points intermediate the ends thereof are the opposed sleeves or collars 15 having inwardly directed and aligned blocks 16. These blocks 16 have their opposed portions provided with the bearing sockets 17 in which are snugly received the trunnions 18 carried by the opposite ends of a tension pulley 19. One of the trunnions 18 has disposed axially thereof a socket 20 in which is engaged an expansible member 21 herein disclosed as a coil spring. This spring bears against the bottom of the socket 20 and also against the inserted end of a shank 22 threaded through one of the sleeves 15 and arm 6 and extending within the socket 20. By the proper endwise adjustment of the shank 22 tension of the member or spring 21 may be regulated to control the frictional contact of the opposite end of the pulley 19 with the outer end of the adjacent block 16.

Midway its ends the pulley 19 has disposed circumferentially therearound a continuous annular flange 23 which serves as a means to prevent interference one with the other of the two cords or strands C which pass around this tension pulley 19 before reaching the work. These cords or kindred strands lead from the spools S mounted upon the opposed radial arms 24 carried by the shaft 3 at a point rearwardly of the bearing block 2. At points between the arms 24 the shaft 3 is provided with the oppositely disposed tubular guide members 25 through each of which is directed a thread leading from one of the spools S. Each of these guide arms 25, as herein disclosed, is somewhat in the form of a gooseneck and a cord C or kindred strand passes from a spool S through a guide arm or member 25 to and through an axial bore 26 of the shaft 3 and then around the tension pulley 19 hereinbefore referred to and from the tension pulley 19 each of the cords C or kindred strands is selectively threaded through an opening 12 in a flange 10 or 11 herein disclosed however as being in a flange 11. The thread after it passes beyond a flange 11 is adapted to be wrapped or wound around the work B which in the present instance constitutes a core or base member for a slide caster for furniture.

The rear end portion of the shaft 3, as hereindisclosed, is rotatably supported by an outboard bearing 27 which may be mounted upon any desired support and, as particularly illustrated in Figure 1, this bearing 27 provides a mounting for a fixed shaft 23 upon which is rotatably supported a double pulley 29. This double pulley 29 permits a driving connection through the belt 30 with a pulley 31 on the shaft 3 and also a desired driving connection with a suitable source of power. I do not, however, wish to be understood as limiting myself to any particular means for driving the shaft 3.

The platform or table 1 at its end portion remote from the bearing block 2 and also spaced a material distance therefrom is provided with the longitudinally disposed parallel tracks 32 providing guideways for a slide 33 positioned therebetween. The movement of the slide 33, however, in a direction toward the block 2 is limited by contact with the inwardly disposed stop lugs 34 extending inwardly from the inner end portions of the tracks 32. The inner end portion of this slide 33 is provided with an upwardly and rearwardly disposed arcuate head 34 terminating beyond the rear end of the slide 33 and which provides a mounting for a shaft 35 disposed substantially in a vertical direction but on a slight upward and rearward incline as particularly illustrated in Figure 1.

The upper end of this shaft 35 is provided with a socket 36 to receive a tang 37 depending from the core or base member B. When this tang 37 is engaged within the socket 36 the applied core or base member B will rotate with the shaft 35. The shaft 35 is adapted to be intermittently rotated and in timed relation with respect to the revolving of the disk 5. The lower end portion of the shaft 35 has fixed thereto a ratchet wheel 33 with which engages a dog or pawl 39 rotatably mounted, as at 40, upon an elongated member 41. This pawl or dog 39 is provided at its pivoted end portion with a tail extension 42 with which engages a spring 43 suitably anchored, as at 44, to the member 41. This spring 43 serves to constantly urge the bill 45 of the dog or pawl 39 into working engagement with the ratchet wheel 38. upon the platform 1 and in cne end portion this member 41 is provided with a longitudinally disposed slot 46 through which is directed a headed retaining pin 47 mounted upon the platform 1. The opposite end portion of the member 41 is pivotally connected, as at 48, to an end portion of a lever 49. This lever 49 substantially midway its ends is supported. as at 50, upon the platform 1 for rocking movement. The opposite end portion of the lever 49 carries a roller 51 which is normally maintained in the path of travel of the cams 52 by the spring 53. These cams 52 are on the peripheral portion of the disk 5 and, as herein disclosed, are diametrically opposed and project laterally and forwardly from such disk.

As a cam 52 strikes the roller 51 pull is imposed upon the member 41 whereby the dog or pawl 39 by its engagement with the ratchet wheel 33 imparts partial rotation to the shaft 35. As the cam 52 passes from the roller 51 the spring 53 imposes reverse rocking movement to the lever 49 with a return movement to the member 41 to bring the dog or pawl 39 again in position to impart rotation to the shaft 35 when the second cam 52 engages the roller 51. The extent of the intermittent rotation of the shaft 35 depends upon the extent of endwise movement of the member 417 The ratchet wheel 38 also has coacting therewith a resilient holding dog or pawl 54 whereby the shaft 35 is effectively held against retrograde rotation. This pawl 54 is secured to a side face of the head 54 of the slide 33 by a headed shank 55 threading into the head 34 and directed through the pawl 54. This shank 35 is also disposed through a plate 56 overlying the connected The member 41 lies ried by the slide 33.

nd po tion, of t e cor pawl 54, sai plate havin'gfan inturned flange or'lip' 57 contacting with the dog or] pawl '54at aipoint beyond the head 34 whereby the tension of the dog or pawl 54 with respectto the ratchet wheel 38 can bereg'ulated or, varied as desired upon tightening or loosening the headed shank 55,. The, head 34 has pivotally connected to a side-face thereof, as at 58, an intfirmediate portion of an upstanding rocking arm 59.. The portion of the arm 59 below the pivotal mounting, 5,3 is of alength to overlie the rear .end of a track 32 when'theslide 33 is at the limit of its rearward movement. 1

,Theupper end of the arm 59 is provided with the transversely disposed table 60 which overlies thehead 34 and said table 60 is adapted'to have clampedthereto a cutting blade 61 whereby a cord Cj or kindred. strand may be readily severed when desired. The upper portion of the arm 59 is, urged rearwardly and of course the lowerend portion, forwardly by a spring 62, one end portion of which contacting, with the forward upper edge of the. arm 59 with the opposite end portion bearing againstanupstanding operating post 63 car- An intermediate portion of the spring 62 is operatively engaged by a coil 64 with the pivot member 58 for the arm 59.

As the slide 33 is moved forwardly the contact of the lower portion oi the arm 59 with the rear and or the adjacent track, 32 will cause the upper endportion of the arm 59 to swing forwardly and tions the cords C or kindred strands will be disdownwardly and to maintain such a position throughout the period. the lower extremity of the arm 59 is in contact with theupper surface of the track 32. When the arm is in this position the cutting blade 61 is thrown back, and down out of -openings 65 are disposed through the platform 1' and are spaced apart lengthwise thereof and between. the tracks32. The spacing of the openings 65 is such as to allow the'post 63 to effectively lock or hold the slide 33 at the limit of its move- ;ment in either direction. 7, V

In, use with the slide, 33 in its forward position av core or base member B is engaged with the shaft 35 whereupon the slide is moved to its rearmostpositiion which will position a portion of the 1; applied core or base member B between the flanges v liof the, sleeves 9. The operator initially holdsthe ends of thecords C or kindred strands in a position as indicated by dotted lines in Fig--' ure 4, and as the shaft 3 rotates the sleeves 9, ormore particularly the flanges 11 thereof, will travel around the applied core or base member B resultingin a desired wrapping of the cords or strands therearound. Upon a half revolution of the disk 5. the shaft 35 will be intermittently rotated with the result that upon successive operaposed across the outer or uppermost face of the applied core or base member B in a direction chordal thereof. These wrappings of the cords C will also be disposed between the downwardly disposed spaced fingers extending around the periphery of the core or base member B or more particularly within the notches 66 between such fingers. The slide caster as produced by the apiparatus as herein disclosed is particularly described and illustrated ina copending ,applieation filed on even date herewith, Serial No. 667,915. f It is also believed to be apparent that as are suit of the intermittent rotation of the shaft 35 the cords or kindred strands C will be disposed over the core or base member 13 in crossed relation whereby said cords will be properly distributed from the core or base member; After a sufficient number of wrappings have been made, the slide 33 is moved forwardly so that the operator can remove the finishedcaster and apply a new core or base member B. Promptly upon the application of the new core or base member B the operator holds the finished core until asuiiicient number of wrappings have been made around the second core or base memher after which the cords are severed by proper engagement with the blade 61. It is to be understood, however, that before such cutting of the cords and immediately after applying the second or succeeding core or base member, the operator moves the slide 33 rearwardly so that the shaft 35 or more particularly the core or base member B carried thereby will be in proper position with respect to the winding unit.

Immediately adjacent to the forward or free ends of the arms 6 the platform 1 has extending upwardly therefrom a protectingor guard plate 67, said plate in its lower central part being pro-.- vided with a substantially triangular opening 68 with its apex upwardly disposed. This opening 68 is of such a size as to offer nohindrance or obstruction to the rearward movement of the slide 33 with a core or base member B applied to the shaft 35.

From the foregoing description it is thought to be obvious that a winding apparatus constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some changegand modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation oi? the 'several parts herein shown in carrying out my inention. in practice except as hereinafter claimed.
